Okay, I will create an issue. Thank you for your help!

The first model is from the forgedebugmodelanimation test mod with the name 'rotatest' and the second is from my mod with the name 'crusher'. (https://github.com/SE7-KN8/RealReactors/blob/master/src/main/resources/assets/realreactors/blockstates/crusher.json)

Yes, that's true^^. You can find the code for the mod here: https://github.com/SE7-KN8/RealReactors But additionally, I have to say that I have this problem also on a clean forge environment with just the test mods enabled. So I don't think the issue comes from my mod.

I have an issue with the forge animation API: https://drive.google.com/open?id=1oDEiNbt2hZqKMh-dXamyBP3twBdPuxU2 As you can see in the video, the issue is that sometimes the submodel gets black. (Sometimes I have to break and place the block again to reproduce the issue) I tested it in forge 14.23.4.2705. The first model is from the forge test mod and the second one is from me.
